Abstract:
An information theory description of finite systems explicitly evolving in time is presented. We impose a MaxEnt variational principle on the Shannon entropy at a given time while the constraints are set at a former time. The resulting density matrix contains explicit time odd components in the form of collective flows. As a specific application we consider the dynamics of the expansion in connection with heavy ion experiments. Lattice gas and classical molecular dynamics simulations are shown. © 2007 American Institute of Physics.

- The ensemble of events dynamically prepared may be characterized by an information about size and shape more complex than the simple mean square root radius. In this case other constraints can be introduced such as R̂4 if the radii fluctuations contain non-trivial information or Q̂2, 2Ẑ2, X̂2, Ŷ2 if the system is not spherical in average but has a finite quadrupole deformation; Chomaz, P., Gulminelli, F., Juillet, O., Ann.
